UNIT 5 PERMANENT MAGNET SYNCHRONOUS MOTORS . This assumption can be made because of the large air gap usually found in permanent magnet synchronous machines. the former requires a separate DC source energizes the rotor windings and generates a magnetic field while the latter describes a synchronous motor whose rotor is designed to be magnetized by the rotational stator magnetic field and rotates with it. The system top-level model is shown in Fig. When three phase winding of stator is energized from 3 phase supply, rotating magnetic field is set up in the air gap. Internal endogenous reluctance R mo of the permanent magnet, assembly space reluctance R 1 and R 2 and the magnetic bridge reluctance R b are marked. There are no windings, slip rings and brushes.
